Air pressure?
You can adjust the air pressure?
Who knew there's a Schrader valve on top of that blue tank!
Not me!
You really don't seem to observe very much for all the looking you
describe...

Looking for the Schrader valve, I removed the wrong cap:

The nut is welded onto the tank to screw in a hook eye to move it with...

Bladder pressure charge seems to be at 18 psi, which is well below the
original precharge of 38 psi (if that 39 psi is accurate):

And you should recharge it (when it is as empty as you can possibly get
it) to -2 psi from the pressure switch cutoff pressure. Leaving it so
low cam lead to premature failure of the diaphragm from over-flexing.
....
I then turned the circuit breaker on and the pump ran for about three
minutes where the contacts clearly cut off in this position automatically:

At that "full" point, my bladder gauge was pegged at above 60PSI:

While the pump gauge read about 62 psi:

That's suggestive that the overall system is still actually operating at
the nominal 60-40 setpoint range, not something approaching 70-75 psi.
I don't trust that old gauge much; you need to get a wider range gauge
to read the pressure in the pressure tank accurately in order to know
where your pressure switch setpoint is and to precharge it correctly for
the operating pressure.
I'd take the other gauge out to check it actually does zero...where the
50+ psi came from with the pressure tank empty and showing 20 and only
5 psi or so from the external tank head is a mystery (unless the well
pump was on?).
